摘要
单摆忽略摆线的质量和摆球的体积，所得单摆的微振动方程有着较大的误差，文中用双摆修正单摆，可以得到较为精确的结果．
The mass of the pendulum cord and the volume of the pendulum sphere are neglected in a simple pendulum. The obtained equation of the small oscillations of the sim-ple pendulum has larger error. This paper revises the simple pendulum by a double pendu-lum.Themore accurate results have been obtained.
